The Gunners’ current shirt manufacturer deal expires in summer 2014 and the offer from Adidas is reported to be a huge improvement on the £13million-a-year that Nike are paying

Arsenal are set to end their 18-year association with Nike and sign a £25million-a-year kit deal with Adidas, according to reports on Friday.

The Daily Telegraph claims Adidas, who ended their association with Liverpool last season, are keen to open another association with a major Premier League club.

The Gunners’ current shirt manufacturer deal expires in summer 2014 and the offer from Adidas is reported to be a huge improvement on the £13million-a-year that Nike are paying.

Arsenal’s kits were previously manufactured by Adidas between 1986 and 1994 and it appears that the German company have taken a strategic decision to target London clubs. They already manufacture Chelsea’s shirts and are believe to be in negotiations over a deal with Fulham.

Arsene Wenger’s team are currently the third-highest shirt sellers under the Nike label, with 800,000 shirts being purchased each year. Only Manchester United and Barcelona sell more.

As well as Chelsea, Adidas already manufacture the shirts of Stoke City, Swansea City, West Brom and Sunderland.

Continentally, their portfolio also includes giants Real Madrid, Bayern Munich and AC Milan. Nike have already agreed a deal with Manchester City beginning in 2013, to add to their existing ones with Manchester United and Everton.
